A very unstable airmass was able to sustain itself overnight across the region during the predawn hours of June 6th and this atmosphere continued into the afternoon hours as well. A strong ridge of high pressure was noted across the Great Basin and this left the Four State Region under the influence of northwest flow aloft.

The episode as NWS SHV wrote it up.
A very unstable airmass was able to sustain itself overnight across the region during the predawn hours of June 6th and this atmosphere continued into the afternoon hours as well. A strong ridge of high pressure was noted across the Great Basin and this left the Four State Region under the influence of northwest flow aloft. This type of flow typically can produce strong to severe thunderstorms, along with flash flooding when upper level disturbances move in this flow.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Shreveport, LA wrote its last area forecast discussion before the first event at Jun 6, 3:34 AM CST, 46 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 434 AM CDT THU JUN 6 2013 .DISCUSSION... FCST HAS BECOME MORE COMPLEX OVER THE LAST 24 HOURS. SHORTWAVE TROUGH THAT WAS RESPONSIBLE FOR THE SRN PLAINS MCS 24 HOURS AGO IS NOW JUST EAST OF THE MS RIVER. THIS SHORTWAVE HAS PROVIDED JUST ENOUGH ASCENT ALONG AN OUTFLOW BOUNDARY FROM YESTERDAY/S CONVECTION TO INITIATE WIDELY SCT TSTMS ALONG AND SOUTH OF THE I-20 CORRIDOR. INTENSITY AND COVERAGE HAS BEEN SLIGHTLY HIGHER ACROSS N CNTRL LA IN THE VICINITY OF A THETA-E RIDGE. WEAK MID- LEVEL FLOW HAS ALLOWED FOR SLOW MOVEMENT AND MERGING OF INDIVIDUAL CELLS INTO CLUSTERS. COMBINED WITH THE ABUNDANT MOISTURE IN PLACE...THIS HAS LED TO SOME HEAVY RAINFALL AMOUNTS ALREADY ACROSS THE ERN ZONES. CANNOT RULE OUT AN ISOLATED SEVERE WIND GUST WITH THIS ACTIVITY AS SOME OF THE STRONGER CELLS COLLAPSE. THIS ACTIVITY SHOULD CONTINUE TO SLOWLY MOVE ESEWD AND EVENTUALLY OUT OF THE CWA BY LATE MORNING. THE FOCUS NOW SHIFTS TO THE CONVECTION BACK TO THE WEST ACROSS SRN OK/N TX. LATEST RADAR LOOPS INDICATE THAT AN MCV IS BEGINNING TO DEVELOP BETWEEN KSPS AND I-20. OUTFLOW BOUNDARY IS ALSO VISIBLE ON KFWS RADAR LOOPS AND IS BEGINNING TO OUTRUN THE MAIN CONVECTIVE COMPLEX. THE MOST ORGANIZED CONVECTION WILL LIKELY BE ON THE NE SIDE OF THE MCV AND MAY JUST GRAZE THE NW ZONES. ACTIVITY ON THE SOUTH SIDE OF THE COMPLEX SHOULD REMAIN MORE SCT IN NATURE AND INTENSITY SHOULD CONTINUE TO DECREASE THROUGH THE DAY. THESE TRENDS WERE PICKED UP QUITE WELL BY THE HI-RES HRRR AND WRF MODELS. THE 00Z RUNS OF THE NAM/GFS/ECMWF STILL PORTRAYED AN MCS MOVING FROM NORTH TO SOUTH AHEAD OF THE COLD FRONT...A SCENARIO WHICH HAS NOT MATERIALIZED. THUS...CONSIDERABLE WEIGHT WAS PUT INTO THE HI-RE MODEL SOLUTIONS FOR THE FIRST COUPLE OF FCST PERIODS. GIVEN THE LACK OF VERIFICATION AND POOR INITIALIZATIONS THUS FAR OF THE LARGER SCALE OPERATIONAL MODELS...CONFIDENCE IS MUCH LOWER FOR WIDESPREAD RAINFALL. HOWEVER...THE MCV...THE PRIMARY UPPER TROUGH AXIS...AND COLD FRONT WILL ALL ARRIVE IN THE AREA AT ABOUT THE SAME TIME. COMBINED WITH ABUNDANT MOISTURE AND DAYTIME HEATING...THIS SHOULD BE ENOUGH FOR AT LEAST SCATTERED SHWRS/TSTMS ACROSS MUCH OF THE AREA THIS AFTERNOON. COVERAGE WILL LIKELY BE HIGHEST ACROSS THE SRN HALF OF THE AREA CLOSER TO THE COLD FRONT. PRECIP CHANCES SHOULD GRADUALLY DIMINISH FROM NW TO SE BEGINNING TONIGHT AND CONTINUING THROUGH FRIDAY AFTERNOON AS THE UPPER TROUGH SLOWLY MOVES SE AWAY FROM THE AREA. NO SIGNIFICANT CHANCES FOR RAIN ARE EXPECTED BEYOND FRIDAY THROUGH THE REMAINDER OF THE FCST PACKAGE. MEDIUM RANGE MODELS ARE HINTING AT THE POSSIBILITY OF MORE RAIN CHANCES SUNDAY AND POSSIBLY INTO EARLY MONDAY AS AN UPPER RIDGE OVER THE SW CONUS AMPLIFIES THE NWLY FLOW ALOFT. UPPER RIDGE IS EXPECTED TO MOVE EWD AND BUILD OVER THE SRN PLAINS BY THE MIDDLE OF NEXT WEEK WHICH WILL KEEP RAIN CHANCES IN THE SLIM-TO-NONE CATEGORY AND WILL ALLOW HIGH TEMPS TO GRADUALLY RISE INTO THE MID 90S. RAINFALL OVER THE NEXT 24 TO 36 HOURS WILL BE KEY FOR TEMPERATURES GOING INTO NEXT WEEK. IF RAINFALL AMOUNTS ARE LOWER THAN EXPECTED...THE HIGH TEMPERATURE FCSTS BEYOND MONDAY COULD VERY WELL BE TOO LOW. /09/ && .AVIATION... WIDELY SCATTERED CONVECTION EARLY THIS MORNING...AS EXPECTED IN THE VCNTY OF A FEW OF OUR TERMINALS...ESPECIALLY NEAR THE SHV/MLU TERMINALS. EXPECT COVERAGE TO REMAIN WIDELY SCATTERED THROUGH THE EARLY MORNING HOURS WITH AN INCREASE IN COVERAGE LIKELY THROUGHOUT THE DAY. WILL CONTINUE WITH VICINITY WORDING THROUGHOUT THE DAY PERHAPS WITH A TEMPO GROUP OR TWO WARRANTED WHERE COVERAGE IS EXPECTED TO BE GREATEST. ONCE THESE STORMS DECAY...OBVIOUSLY STRONG GUSTS WINDS WILL BE A PROBLEM...ALONG WITH A QUICK REDUCTION IN VISIBILITY WITH SMALL HAIL ALSO POSSIBLE BUT THIS WILL BE VERY LOCALIZED WITH AN AMD PROBABLY THE BEST WAY TO HANDLE THIS IN THE 12Z TAF PACKAGE.
